Other locks

White’s left wing is not developed well. Pieces 36 and 46 are not active. To activate these, white played 46 – 41 36 – 31 41 - 36 building the formation 27/31/36. Black (Ainur Shaibakov) anticipated this plan by locking white’s left wing.

1… 2 – 8!

2.46 – 41 11 – 16

3.36 – 31 17 – 21

4.41 – 36 8 – 13

5.40 – 35

Going to the graveyard 27 – 22? 18 x 27 31 x 22 12 – 18 simply loses the piece. Now black makes a strong exchange gaining space. After this black has a lot of possibilities, while white is running out of moves.

5… 23 – 29!

X 23 18 x 29

White will be frozen out, for example: 7.39 – 34 29 x 40 8.35 x 44 24 – 29 44 – 40 14 – 20 40 – 35 20 – 24 28 – 22 12 - 18 B+

1.45 – 40?

White played this move to make a formation 34/40. At 24 – 30 he can play 27 – 22 18 x 29 34 x 14 13 – 19 14 x 23 8 – 13 40 – 34 12 – 17 34 – 29 with the winning threat 29 – 24 +.

Black prepares an arrow lock.

1… 18 – 23

White has little space to play. He must fly to square 22.

2.28 – 22 24 – 29!

X 24 19 x 30

Since white is locked, he has one playable piece left.

4.47 – 42 12- 17

X 11 16 x 7

6.27 – 22 loses because of 8 – 12 7.42 – 38 (7.32 – 27 7 - 11 8.42 – 38 13 – 19 9.38 – 33 12 – 17 etc. B+) 12 – 17! 8.22 x 2 26 – 31 9.2 x 28 31 x 22 and black wins: 10.34 – 29 30 – 34 11.39 x 30 25 x 45 12.29 – 24 45 – 50 13.44 – 40 35 x 44 14.24 – 19 22 – 28! 15.32 x 23 44 – 49 16.23 – 18 50 – 17 17.19 – 14 49 – 27 +

6.42 – 38

Black could have forced a win by playing 6… 13 – 18! 7.38 – 33 8 – 13

1) 8.33 – 28 13 – 19 9.28 – 22 26 – 31! (stick move) 10.22 x 24 31 x 42 B+

2) 8.33 – 29 13 – 19 9.29 – 24 26 – 31! (stick move) 10.24 x 22 31 x 42 B+

1.39 – 34!

Black can’t take the Bomb shot in this situation. If piece 4 was at 5 the Bomb should would win black a piece. Black should anticipate white’s next moves: 34 – 29 23 x 34 40 x 29 and play 2 – 7. Then he is able to remove the dangerous piece at 29: 18 – 23 29 x 18 12 x 23.

After 1.39 – 34 2 – 7 2.44 – 39 (or 2.34 – 30) black can go to the graveyard without problems: 24 – 29 33 x 24 20 x 29.

1… 1 – 6?

X 34

3.40 x 29 2 – 7

It’s too late for this move now. White freezes out his opponent.

4.28 – 22!

Black has left only the poor 4… 4 – 9, but after 5.44 – 39 19 – 23? is no good and black has to sacrifice.

1.39 – 34!

White takes a fork lock at a different spot of the board than we are used to.

White is threatening the Coup Philippe 34 – 30 25 x 34 38 – 33 29 x 27 31 x 22 18 x 27 40 x 20.

1… 19 – 24 is followed by 34 – 30 25 x 34 32 – 28 23 x 43 48 x 17 +.

1… 3 – 9

2.32 – 27! 14 – 20

2… 19 – 24 is met by 3.38 – 33 29 x 38 4.49 – 43 38 x 49 5.48 – 32 49 x 21 6.26 x 10 +.

At 2… 7 – 11 white can take a coup Philippe again.

3.38 – 32!

The threat 32 – 28 is not stopped by 9 – 14 and 19 – 24 is punished by 32 – 28 +.

3… 18 – 22

X 18 13 x 22

X 31

X 27

The death blow. There is no good answer to the threatening 32 – 28.

White has a semi-fork that works as a perfect lock here, because white prepares a shot at 17 – 21.

1.33 – 29! 15 – 20

The only move. Both 17 – 21 and 19 – 23 are answered by 2.25 – 20!!

2.42 – 37!!

Black is tactically frozen out.

2… 19 – 23

X 29

X 33

X 10

Black has attacked piece 27 several times with 17 – 21. White can stop the attack tactically.

1.41 – 37! 17 – 21?

2.37 – 32 21 – 26

X 28

X 31

X 27 13 x 24

X 4

So black can’t play 17 – 21. A logical variation is 1.41 – 37 13 – 19 2.37 – 32 9 – 14 after which white’s position is much better.

Gantwarg – Galkin

X 30

X 25 23 x 34

3.39 x 30 11 – 17?

Too slow. The only defence was 3… 13 – 19.

4.30 – 24

White’s strategy is helped by tactical means. Black can’t play 4… 17 – 21 because of the nice shot 5.38 – 33! 21 x 32 6.24 – 20 15 x 24 7.33 – 29 24 x 33 8.43 – 38 choice 9.48 x 10 +.

At 4… 14 – 19 white forces a win by 5.38 – 33! 19 x 30 6.35 x 24 3 – 9 (17 – 21 is answered by a 33 – 29 24 – 20 43 – 38 shot) 7.33 – 29! With the decisive threat 29 – 23 +.

4… 3 – 8

5.43 – 39 17 – 21

X 32

7.38 x 27 12 – 17

8.39 – 34 8 – 12

White would use the free move after 8… 17 – 21 to play 9.34 – 30 21 x 32 10.24 – 20 15 x 24 11.30 x 10 +.

9.34 – 29

Black couldn’t parry the 29 - 23 threat and surrendered.

Diagram next column: White breaks the semi-fork in order to surround black’s centre pieces.

X 31

X 27

White threatens to attack the centre playing 33 – 28. At 23 – 29 white attacks again 28 – 23 and at 14 – 19 30 – 24 is decisive.

2… 2 – 8

3.33 – 28! 4 – 10

X 19 13 x 24

X 19 14 x 23

6.35 – 30!

This piece is on its way to the strategic square 24. Black will be frozen out. He can never play piece 6 because of 32 – 28 +.

6… 10 – 14

7.30 – 24 8 – 13

8.39 – 34 14 – 19

9.34 – 30

The job has been done. Black ran out of moves.

White saw no trouble ahead, but after 1. 28 – 23? he was trapped in a beautiful way:

1.28 – 23? 13 – 18

2.34 – 30? 20 – 25!

C 31.8

The endgame

When the number of pieces gets smaller and kings come into play, the game usually gets even more difficult than it already is.

When the opponent gets a king and the king can’t be caught before long, only being dominant can win the game. Being dominant is only possible having at least 4 pieces.
